더블 스트라크 캐피탈 Q ℚ
기호 의미
The set of rational numbers ℚ = {m/n} consists of numbers that can be expressed as ordinary fractions (for example, 4/3). In decimal representation, they can be finite or repeating decimals, such as 4/3 = 1.333... The term ‘rational‘ comes from the Latin word ‘quotient‘, which furthermore developed in English. It's interesting enough that the set ℚ is also countable (equivalent in cardinality to the set of natural numbers ℕ).
The sets ℕ , ℤ , ℚ , ℝ , ℂ are often written in bold font (for example, in the works of Nicolas Bourbaki) or as double-struck letters on blackboards and manuscripts. The usage of double-struck font in printed texts was introduced by American mathematicians and became widespread with the famous textbook on complex analysis by Gunning and Rossi, published in 1965.
‘더블 스트라크 캐피탈 Q‘ 기호는 ‘수식 기호 문자‘ 블록의 ‘글자 모양의 기호‘ 서브블록에 포함되어 있으며 1993년에 Unicode 버전 1.1의 일부로 승인되었습니다.
